Description

  The present invention relates to a terminal crimping applicator used in a terminal crimping device, and in particular, an upper unit having a pressing member and a lower unit having a base on which an anvil is formed are separated. The present invention relates to a terminal crimping applicator.

  Conventionally, as a terminal crimping applicator, an elevating member that moves up and down by a power mechanism disposed on the upper side of a support member vertically installed on a terminal crimping device, and a press attached to the lower end of the elevating member What comprises a member and the base which is arrange | positioned under the support | pillar member and in which the concave anvil was formed in the upper surface is known. According to this, when the pressing member moves downward by the power mechanism, the crimp terminal is crushed between the tip of the pressing member and the concave anvil.

  The crimp terminals are connected in series by a plate-like carrier, and are sequentially fed onto the anvil of the base by a terminal transport mechanism. The terminal transport mechanism is mechanically linked to the operation of the pressing member, that is, the operation of the power mechanism, and each time the crimp terminal is crushed and the pressing member is displaced from the bottom dead center to the top dead center, the locking claw portion The carrier is moved in a predetermined direction, and the crimp terminals are sequentially fed onto the anvil. The plate-like carrier is provided with locking holes for locking and positioning, and the locking claw portions are locked to the locking holes.

  In addition, as a terminal crimping apparatus using a terminal crimping applicator, an apparatus including an electric wire feeding mechanism for moving an electric wire to a predetermined position, and a cutting mechanism for cutting an electric wire and removing a covering material at an end of the electric wire Is also known. According to this, first, the covering material on the front end side of the electric wire is removed, and the front end of the electric wire is inserted into the crimp terminal placed on the anvil of the base. In addition, after the crimping terminal is crushed, the electric wire with the crimping terminal crimped is fed by a predetermined length by the wire feeding mechanism and cut by the cutting mechanism. In this way, every time the crushing operation is performed, the movement operation (discharge operation) and the cutting operation of the electric wire after crushing are performed, and subsequently, the covering material removal operation and the feeding operation to the crimp terminal are sequentially performed. Done.

At the time of filing this application, the applicant knows the following as a document in which the above technical information is described.
JP 2000-208228 A

  However, in the above-described terminal crimping applicator, the terminal transport mechanism cannot be handled alone because the terminal transport mechanism is mechanically linked to the operation of the pressing member. In other words, since the lifting member for operating the pressing member and the power mechanism of the terminal crimping device must be handled integrally, the structural unit handled as one unit has been enlarged. For this reason, maintenance becomes difficult and much labor is required for the replacement work. In particular, since the shape of the pressing member and anvil varies depending on the shape of the crimp terminal, if there are many types of crimp terminals to be processed, many types of units must be provided for storage. A large warehouse was required, and a lot of time was required for the replacement work including taking out and storing the unit. Therefore, it has been difficult to increase productivity under the current production system in which high-mix low-volume production is mainstream.

  In addition, since the vertical reciprocating motion of the pressing member has to be converted into a horizontal motion of conveying the crimp terminal, the mechanical configuration has been complicated. Moreover, although a long stroke is not required only by crushing the crimp terminal, a long stroke is required to transport the crimp terminal in the horizontal direction, and this facilitates the enlargement of the unit.

  In addition, locking holes are formed in the carrier at predetermined intervals so that the crimp terminals can be conveyed. The shape of the locking holes varies depending on the manufacturer and is small, so the locking holes The shape of the locking claw portion to be locked in the hole is complicated, and high positioning accuracy is required.

  Furthermore, in the above-described terminal crimping applicator, the pressing member and the terminal transport mechanism are mechanically interlocked, so that the structure behind the anvil is connected to each other, that is, the rear of the anvil is blocked. It was a structure. For this reason, in a terminal crimping device using a conventional terminal crimping applicator, the wire with the crimped terminal crimped cannot be sent straight (ie, behind the anvil) as it is, for example, crimping from the cutting position of the wire. The wire feed mechanism is rotated to move the wire to the terminal crushing position, and after the crushing, the wire feed mechanism is further rotated to change the wire feed direction to another direction. There was a need. In this case, an extra process of rotating the entire wire feeding mechanism is required, which has been a factor of increasing the processing time.

  Accordingly, in view of the above situation, the present invention reduces the burden of replacement work by separating the terminal transport mechanism from the pressing member and the like, facilitates maintenance, and further reduces the size and simplification of the entire apparatus. It is another object of the present invention to provide a terminal crimping applicator that can move an electric wire linearly.

The applicator for terminal crimping according to the present invention includes: a base having an anvil formed on the upper surface; an upper unit having a pressing member that collaborates with the anvil of the base and crushing the crimp terminal; A lower unit provided separately from the unit and provided with the base and terminal transport means for sequentially supplying the crimp terminals connected in series by a plate-like carrier to the anvil of the base; In the terminal crimping applicator, the terminal conveying means includes a base member, a latching claw part that can be latched to the crimping terminal or a part of the carrier, and holding the latching claw part to the base member. A slide member that is slidably supported in a substantially horizontal direction, a first power mechanism that moves the slide member in a substantially horizontal direction, and the locking claw that is held by the slide member by the first power mechanism Through the department As well as guides the movement direction scissors and stop mechanism said carrier to stop the inertial motion of the carrier to be transported, and a groove-shaped guide portion to project a plurality of crimp terminals coupled to the carrier from the opening portion The slide member is disposed below the guide portion, allows the locking claw portion to protrude and retract toward the guide portion side, and when the slide member is in a retracted position away from the anvil. the claw portion in a part of the crimp terminal or the carrier you support to the locking impossible "is intended to be configured. Here, the configuration of the “first power mechanism” is not particularly limited, but for example, it can be configured from a cylinder connected to a slide member.

  By the way, if only one of the locking claws is locked to a part of the crimp terminal or the carrier and there is a gap between the other, the inertia movement acts by being conveyed to the crimp terminal. Even if the locking claw stops, the crimp terminal moves further by inertial movement. In particular, the inertia increases as the conveying speed is increased, and there is a possibility that the crimp terminal cannot be accurately fed onto the anvil.

  According to the terminal crimping applicator of the present invention, the crimping terminals are sequentially supplied onto the anvil of the base by the terminal conveying means. Specifically, the terminal conveying means moves the slide member in a substantially horizontal direction by the operation of the first power mechanism. Since this slide member holds the locking claw, if the locking claw is locked to a part of the crimp terminal or the carrier by the movement of the slide member, the crimp terminal is connected in series by the carrier. Moves in a substantially horizontal direction together with the slide member. By this movement, one crimp terminal is fed onto the anvil. At this time, the inertial motion of the carrier is braked by the restraining mechanism, and the crimp terminal is restrained at a desired position. And whenever a slide member is moved, a crimp terminal is supplied in order on an anvil.

  The terminal conveying means including the first power mechanism is separated from a mechanism for crushing the crimp terminal from above, that is, a pressing member, and is arranged in a state of being separated from each other. Accordingly, the upper unit such as the pressing member and the lower unit such as the terminal conveying means can be individually managed or individually replaced. For this reason, the structural unit of a unit is reduced in size and the burden in storage and replacement work is reduced. Moreover, since a space is formed between the upper unit and the lower unit, the electric wire fed from the front can be sent to the rear side of the anvil.

  Further, since the base is fixed to the base member, the distance between the base member of the terminal transport mechanism and the anvil is always constant. For this reason, adjustment work, such as a movement amount and a moving direction of a crimp terminal, becomes unnecessary, and the burden of the operator in replacement | exchange etc. can be further reduced.

  Furthermore, since the inertial motion of the carrier in which the crimp terminals are connected in series can be stopped, the conveyance speed of the crimp terminals can be increased, and the efficiency of the terminal crimping apparatus to which the applicator for terminal crimping of the present invention is applied can be improved. It becomes possible to raise.

  By the way, in the terminal crimping applicator according to the present invention, “the upper unit is configured to remove a crimping member clamped by the pressing member after the crushing operation, and to move the scraping member substantially vertically. It is possible to adopt a configuration that further includes a two-power mechanism.

  According to this terminal crimping applicator, even if the crimping terminal is clamped by the pressing member after the terminal is crushed, it can be removed. Therefore, it can be avoided that the crimp terminal is held between the pressing members and the apparatus cannot be stopped.

  According to this terminal crimping applicator, when the locking claw portion protrudes from the lower side of the guide portion to the guide portion side, the distal end side of the locking claw portion is placed on the side surface of the crimping terminal protruding from the opening portion of the guide portion. It becomes possible to contact. And when the latching claw part is moved in the horizontal direction by the slide member, the latching claw part presses the side surface of the crimp terminal, and the carrier and the crimp terminal can be moved along the groove-shaped guide part. Become. In addition, since the latching claw part is supported so that it can protrude and retract, it switches to the state which does not press a crimp terminal by immersing. That is, when the slide member is moved in the transport direction, it is locked when moving in the transport direction by switching the state of the locking claw portion between the case where the slide member is moved in the transport direction and the case where the slide member is moved in the counter transport direction. In some cases, it is possible not to be locked.

  Further, when the slide member is in the retracted position, the locking claw portion is immersed. That is, since the latching claw portion does not contact the carrier and the crimp terminal, when the crimp terminal connected by the carrier is removed from the terminal conveying means, the latching claw portion does not interfere with the conveyance direction. Makes it possible to easily remove the carrier connected to the crimping terminal in the opposite anti-conveyance direction.

  Furthermore, in the terminal crimping applicator according to the present invention, “the terminal conveying means is configured to move the locking claw portion upward so that the height of the tip portion of the locking claw portion becomes the height of the guide portion. It further includes an elastic member to be urged, and the distal end portion of the locking claw is formed in a tapered shape in which the side on the conveyance direction side is substantially vertical and the side on the side opposite to the conveyance direction is inclined. '' be able to. Here, the “side in the transport direction” is a side that comes into contact with the crimp terminal when the locking claw portion is moved in the transport direction. Further, the “side on the side opposite to the conveyance direction” is a side that comes into contact with the crimp terminal when the locking claw portion is moved toward the opposite side.

  According to this terminal crimping applicator, it is possible to make the locking claw part appear and disappear without providing a power mechanism. That is, the latching claw portion is urged upward by the elastic member, and the side on the conveyance direction side is formed substantially vertically at the tip portion thereof. Therefore, when the latching claw portion moves in the conveyance direction, The side formed in the contact with the side surface of the crimp terminal. At this time, since a force is applied in the horizontal direction to the locking claw portion, the locking claw portion presses the end surface of the crimp terminal without changing in the vertical direction. That is, it is possible to move the crimp terminal while being locked to the crimp terminal. On the other hand, when the locking claw portion moves in the counter-conveying direction, the downward inclined side comes into contact with the side surface of the crimp terminal. At this time, since a force is applied obliquely downward to the locking claw portion supported so as to be able to protrude and retract in the vertical direction, the locking claw portion changes in the immersion direction. For this reason, a latching claw part moves below the crimp terminal, without being latched by the crimp terminal. Therefore, it is possible to move the crimp terminal and the carrier only in one direction with a very simple configuration.

  Further, in the applicator for terminal crimping according to the present invention, “the terminal conveying means further includes a plurality of guide auxiliary members that partially close the opening portion of the guide portion, and the guide auxiliary member is a gear-shaped rotating body. And the gap between the teeth is at least wider than the width of the neck portion connecting the crimp terminal and the carrier, and at least two teeth can simultaneously block the opening of the guide portion at the same time. It can be a “formed” configuration.

  By the way, the guide part is composed of a groove-like member in which only the plate-like carrier is sandwiched, and the crimp terminal protrudes from the groove and is supported, so when transporting the crimp terminal and the carrier, from the opening part of the guide part There is a risk that the carrier will fly out (ie, deviate from the guidance). In this case, it is difficult to guide the crimp terminal and the carrier in an appropriate direction.

  However, according to the terminal crimping applicator of the present invention, the plurality of guide auxiliary members are made of a gear-shaped rotating body, and teeth positioned on the front side of the neck portion connecting the crimp terminal and the carrier are pushed by the neck portion. The front teeth eventually dip below the guide part, but before the front teeth dip, the rotation of the rotating body causes the next tooth to protrude to the back of the neck, opening the guide part. Since the portion is partially blocked, the carrier is guided in an appropriate direction without jumping out from the guide portion. In addition, since the guide auxiliary member is a gear-like rotating body, the resistance during insertion and extraction of the carrier into the guide portion can be reduced as much as possible, and the guide auxiliary member has a simple configuration. It is possible to facilitate the labor required for the configuration.

  Furthermore, in the terminal crimping applicator according to the present invention, “the restraining mechanism is configured such that the press contact portion that press-contacts the carrier, the contact portion that contacts the slide member, and the press contact portion and the contact portion are integrated. A rotating member that is rotatably supported by the base portion, and the sliding member abuts on the abutting portion, whereby the pressing portion rotates in the direction of the carrier, and the pressing portion Can be configured such that the inertial movement of the carrier is stopped by being pressed against the carrier.

  According to this terminal crimping applicator, the inertial motion of the carrier can be restrained by operating the restraining mechanism without providing a power mechanism. In other words, the direction of the linear motion of the slide member is changed by the rotating member, and the press contact portion is strongly pressed against the carrier to restrain the inertia motion of the carrier.

  As described above, according to the present invention, by separating the terminal transport mechanism from the pressing member or the like, it is possible to reduce the burden on replacement work, facilitate maintenance, and further reduce the size and simplify the entire apparatus. Furthermore, by using this, it is possible to provide a terminal crimping applicator that can move an electric wire linearly.

The urging force of the spring 55 is converted to the insertion direction of the connected portion 51 by the action surface 57, and the connecting portion 11 is sandwiched between the locking piece 54 and the flange portion 58 formed on the proximal end side of the main body portion 53. It becomes possible to connect the part 11 and the to-be-connected part 51 so that there is no backlash. In addition, although what provided the pair of the locking piece 54 was shown here, it is good also as only one.

  Next, the conveying operation of the crimp terminal 21 in the terminal conveying means 19 of the terminal crimping applicator 6 of this embodiment will be described with reference to FIGS. 4 and 5. In the terminal crimping applicator 6 of this example, the crimp terminals 21 can be sequentially supplied onto the anvil 10 of the base 18 by the terminal conveying means 19. First, the carrier 20 having a series of crimp terminals 21 connected to the guide portion 23 of the terminal conveying means 19 is inserted to a predetermined position.

Be transported.

  5B, when the slide member 34 comes into contact with the contact portion 46 of the restraining mechanism 44, the pressure contact portion 45 rotates counterclockwise together with the contact portion 46. 45 is pressed against the lower surface of the carrier 20, and the carrier 20 is sandwiched between the pressing portion 45 and the pressing member 29, and the movement of the carrier 20 in the left direction is stopped. At substantially the same time, the rotation of the contact portion 46 is also restricted, and the leftward movement of the slide member 34 that is in contact with the contact portion 46 is also restricted. That is, the inertial movement of the carrier 20 is stopped and the carrier 20 is surely stopped. Thereby, the crimp terminal 21 connected to the most distal side among the plurality of crimp terminals 21 is fed onto the anvil 10.

  By the way, since a part of opening part of the guide part 23 is blocked | closed by the two sets of deviation prevention mechanisms 24, the carrier 20 is prevented from jumping out (departing) from the opening part. In particular, the guide auxiliary member 30 is formed of a gear-shaped rotating body, and the width between the adjacent teeth 32 and the teeth 32 is wider than the width of the neck portion connecting the crimp terminal 21 and the carrier 20, and the two teeth 32 are provided. At the same time, it is formed so as to close the opening of the guide portion 23, and any of the teeth 32 always closes the opening, so that the carrier 20 does not jump out of the opening. Moreover, since the guide auxiliary member 30 is rotatably supported, it does not hinder the conveyance of the crimp terminal 21. In this example, two teeth 32 are formed so as to block the opening at the same time, but two or more teeth 32 may be formed so as to block the opening at the same time.

  Then, after feeding the crimp terminal 21 onto the anvil 10, the operation of the cylinder of the first power mechanism is stopped. Then, the pressing mechanism 35 moves rightward on the paper surface by the elastic force of the spring and tries to return to the original position. At this time, the distal end portion of the locking claw portion 36 comes into contact with the crimp terminal 21 on the downstream side. However, since the side 40 on the side opposite to the conveying direction at the tip portion is inclined, a force is applied obliquely downward to the locking claw portion 36, and the locking claw portion 36 resists the elastic force of the spring 37. And descend. That is, without pressing the crimp terminal 21 to the opposite side, the crimp terminal 21 is returned to the original position through the lower part. Thus, according to the terminal conveying means 34 of this example, it is possible to sequentially move the crimp terminal 21 and the carrier 20 only in one direction by reciprocating the pressing mechanism 35 to the left and right.

  Here, in the operation of the terminal crimping apparatus 1 in the present embodiment, the tip of the electric wire L fed out from the electric wire feeding mechanism 2 is sent to the cutting mechanism 4 through one end, the first crimping machine 3A. At this time, the terminal crimping applicator 6 of this example is separated into the upper unit 7 and the lower unit 8, and the electric wire L can pass between them. And the front-end | tip of the electric wire L sent to the cutting mechanism 4 is pinched | interposed with an upper blade and a lower blade, and the electric wire L is sent back by the electric wire feed mechanism 2, and the coating | coated material of a front-end | tip part is removed. Furthermore, the tip of the electric wire L is sent back to the position of the first crimping machine 3A.

  Subsequently, in the first crimping machine 3 </ b> A, the upper unit 7 and the lower unit 8 are lowered and raised, and the tip end of the electric wire L is fed into the crimp terminal 21 located on the anvil 10 of the lower unit 8. Then, the upper unit 7 and the lower unit 8 further approach each other, and the crimp terminal 21 is crushed by the pressing member 9 of the upper unit 7 and the anvil 10 of the lower unit 8, and the crimp terminal 21 is separated from the carrier 20. Is done. Thereafter, the upper unit 7 and the lower unit 8 are raised and lowered so as to be separated from each other.

  The electric wire L is fed by a predetermined length by the electric wire feeding mechanism 2, is gripped by the chuck mechanism 5, is cut to a predetermined length by the cutting mechanism 4, and covers the rear end portion of the cut electric wire L The material is removed, and in the second crimping machine 3B, similarly to the first crimping machine 3A, the crimp terminal 21 is crimped to the rear end portion of the electric wire L, and the electric wire L provided with the crimp terminals at both ends is completed.

  By the way, when the crimp terminal 21 is crushed by the pressing member 9 and the anvil 10, the crimp terminal 21 may be sandwiched by the pressing member 21 and attached to the pressing member 21. Therefore, as shown in FIG. 6, the upper unit 7 has a dropping member 15 slidably held between the pressing members 9 made of two plates, below the piston member 16 of the second power mechanism. The crimping terminal 21 is lowered by the movement of the crimping member, and the crimping terminal 21 sandwiched between the pressing members 9 is removed to prevent the crimping terminal 21 from adhering to the pressing member 9. The operation of the scraping member 15 is preferably performed every time the crimping terminal 21 is crushed.

  As described above, in the terminal crimping applicator 6 according to the present embodiment, the upper unit 7 and the lower unit 8 are separated from each other, and thus can be managed individually. For this reason, the burden on the unit replacement work is reduced, and the unit can be accommodated even in a relatively small place. For example, in the case of a large unit, it has been necessary to store in a warehouse and take out and transport it from the warehouse at the time of replacement. However, by reducing the size, a shelf arranged near the terminal crimping device 1 It can also be accommodated in the drawer and can be replaced easily and quickly. In addition, since the upper unit 7 and the lower unit 8 each have an IC chip built-in, a desired terminal crimping applicator can be found from a plurality of terminal crimping applicators by reading information on the IC chip. Can be easily done. Further, since a mechanism for mechanically interlocking the upper unit and the lower unit is not required as in the prior art, the apparatus is simplified and the manufacturing cost can be greatly reduced.

  Further, in the terminal crimping applicator 6 of the present embodiment, the electric wire L is sent in a straight line by using the space formed between the upper unit 7 and the lower unit 8. For this reason, a mechanism for rotating the electric wire feeding mechanism 3 becomes unnecessary, and the apparatus can be further simplified. Further, since the time required for the rotation processing is reduced, it is possible to shorten a series of processing times and improve productivity.

  Furthermore, in the terminal crimping applicator 6 of the present embodiment, since the inertial movement of the carrier 20 in which the crimping terminals 21 are connected in series can be stopped, the conveyance speed of the crimping terminals 21 can be increased. The efficiency of the terminal crimping device 1 to which the crimping applicator 6 is applied can be dramatically increased.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  That is, in the terminal crimping applicator 6 described above, the guide auxiliary member 24 is a gear-shaped member, but a plurality of protrusions that partially block the opening of the guide portion on a belt wound between two pulleys. It is also possible to provide a configuration. However, if the configuration of the gear-like rotating body is used as in this example, the number of parts can be reduced, the number of movable parts can be reduced, and the manufacturing cost and durability can be increased.
